This card works well with "Valhalla, Hall of the Fallen". Special Summon one high level LIGHT Fairy-type from your hand with "Valhalla", then Normal Summon one other LIGHT monster, and finally Special Summon this card.

If you have another copy of this card in your hand, you may use "Advance Draw" to draw 2 more cards and summon another "Guardian of Order" from your hand.

When you only have "Guardian of Order" and "Honest" in your hand and any one LIGHT-Attribute monster in your field, Normal Summon "Honest", then Special Summon "Guardian of Order", then you can either return "Honest" to your hand or use him along with an attack. When dealing with an even stronger monster(s) than yours, it is recommended that you bring Honest back to the hand.

Another method is to use "Galaxy Knight" while you control a Photon/Galaxy Monster in order to bring back a "Galaxy-Eyes Photon Dragon" in your Graveyard, Special Summoning "Guardian of Order" because "Galaxy-Eyes Photon Dragon", "Galaxy Knight", and the third Photon/Galaxy are all LIGHT Attribute, then Xyz Summon "Neo Galaxy-Eyes Photon Dragon".
